For Sinumerik system applications, Siemens 6FC5357-0BB15-0AA0 provides the function of an NCU 571.5 Processor Module.
Processor and controller modules execute configured control functions, coordinate data from I/O and communication resources, and manage the operating sequence assigned to their control node. The assigned system function should be preserved through installation and service.
Within the assigned control-system position, this product is associated with the Sinumerik family and the CNC controls category. Configuration and compatibility should be confirmed for the exact system in which it will be used. Maintenance planning should reference the installed hardware configuration.
When this product is used for lifecycle support, technicians should confirm the installed revision, connection arrangement, and system assignment rather than assuming interchangeability with a similarly named module. The system's documented hardware assignment should guide placement.
